gives the arc cotangent cot^(-1)(z) of the complex number z.
  • Mathematical function, suitable for both symbolic and numerical manipulation.
  • All results are given in radians.
  • For real z, the results are always in the range -pi/2 to pi/2, excluding 0.
  • For certain special arguments, ArcCot automatically evaluates to exact values.
  • ArcCot can be evaluated to arbitrary numerical precision.
  • ArcCot automatically threads over lists.
  • ArcCot[z] has a branch cut discontinuity in the complex z plane running from -i to +i.
